ATTORNEY,

Patented Feb. 20, 1940' g L NilED STATS ENT F C 2 Claims. (Cl. 7.0+49)The object of my invention is to provide a locking unit adapted forsecurely attaching various movable objects together, or for attachingpar cels such as luggage &c to some fixed object for preventing movingof same, and for many other similar purposes. Another'object is toprovide a flexible cable locking unit that may be readily adjusted andadapted to various size or shape objects, and I where the cable may belockedin any desired poferred form by the construction and arrangement Iof parts more fully hereinafter set forth. Similar parts on the drawingare marked by similar numerals or letters.

Fig. 1 illustrates my invention in its assembled form, showing thegeneral arrangement of its various operating parts. I

Fig. 2 is a sectional view through the cable,

taken on the line 22 of the Fig. 1, showing an elevation of the lockingunit casing and the cable,

channels formed therethrough.

Fig. 3 is an enlarged detail view of the casing 90 and lock mechanism,with the cap plate removed, showing the general arrangement and positionof the automatic lock operating elements and means for engaging thecable walls in any position.

I will now describe more fully the detail construction of my device,referring to the drawing and the marks thereon.

The lock casing A is made of any suitable metal, either formed or cast,and of any desired shape or design, but preferably of a thin, recessed,disc base I having a circular cap plate 2 fitted thererivets or screws3. A cable anchor channel 4 .is formed within the base I, edgewisethereof, and receives the end of a flexible metal cable B'se- 4 curelymounted therein. The flexible cable B is securely attached within therecess 4 by rivets 5, or any other suitable means. An open cable channel6 is formed through the opposite side of the base section I, alsoedgewise thereof, and preferably at an angle to the opposite anchorchannel 4 as is illustrated in Figs. 1 and 3 of the drawing. The cablechannel 6 is of a size to allow the free end of the cable B to passfreely therethrough which may be adjusted to any position 55 therein.The disc base recess a is extended to over and attached to the disc faceby suitable,

open into the cablechannel Gbya receding wall section b, which providesinternal. contact with the cable unites the same isjadjusted through the,loclgcasing, Within (the base recessuis mounted an L-shaped cablelocking cam ,1, hing- 5 edly attached thereon by a pivot pin 8 fixedlymounted, inthe base recess bottom, at'right angles thereto; The cablelocking cam I is prefer ably formed with a concentric hinge bearing 1,and witha semi-recessed corrugated outerend c, 10 designed andpositionedto contact and fit over the exposed cable wall within the recedingrecess 12, and engage therewith whenever the free cable end is forced inthe withdrawal direction within the open cable channel 6; Thehingebearing 15 is supported ,by an adjacent circular segment shoulder g,positioned to receive the cam thrust caused by theconnecting cable load.The cam action will securely lock the cable B therein. To

insure a more effective locking surface, the cable 90 channel 6 isformed with a furtherrecess d, positioned opposite thecorrugatedcam end0, allowing the cam I to slightly depress the cable therein when apulling forceis applied 'to'the cable member. Thelocking earn 1 isfialso formedwith 5 a special operating arm e, positioned approxi-h matelyat rightangles thereto, and is contacted by an operating cam spring 9mounted within the base recess a. The cam spring 9 is designed andstressed to force the cam 1 against the cable B at 30 alltimes, and withsufficient force to engage and lock the cable on any movement thereoftending to withdraw said cable from the channel 6. A

special release key I0, designed to engage a guide B in eitherdirection. Any suitable type of cable may be used, depending uponthepurpose and application to which the cable lock is torbe applied.

The Fig. 3 illustrates one'form of cable locking elements, althoughother types and kinds of cable locking units may be also substitutedtherefor, and might operate equally as well. y Y It is to be understoodthat my device is subject to various modifications in both design andmechanical construction without departing fromthe spirit of myinvention, and I claim not only the ble, and a release key mountablerotatably within structure herein illustrated and described, but anyother form or modification thereof in either cable or looking unit, thatis substantially a substitution of parts and units herein disclosed.

Having fully described my cable look, what I claim as my invention anddesire to secure by Letters Patent is:

1. A cable lock comprising a flexible metal cable, a suitable thin metallock casing fixedly attached to one cable end, said casing being formedsaid casing designed to engage the operating arm and release the camfrom the cable walls.

2. A cable lock comprising a flexible metal cable, a thin disc metallock casing fixedly attached to one cable end by suitable attachingmeans, said casing being formed with an open cable channel edgewisetherethrough for receiving the free cable end therein, a toothed lockingcam formed with a central bearing hub and a side operating arm,pivotally mounted within said casing with the outer cam end positionedto engage the free cable end within the cable channel, said casingalsobeing formed with a cylindrical bearing shoulder positioned oppositethe locking cam arm and concentric with the cam bearing hub andengagable therewith, also formed with a cable recess along its cablechannel opposite the outer cam end, a cam spring mounted within thecasing positioned to engage the cam operating arm and force said camagainst the cable walls, and a key mountable rotatably within the casingdesigned to'engage the cam operating arm and release the cam from thecable Wall.
